UNT 1 REFRIGERATOR ATTACHMENT.

Application led August 3,1918.

To all 'whoml t may concern.'

Be it known that I, DAVID STANFORD, a subject of the Government ofFinland, residing at New York, in the county of New York'and State ofNew York, have inventedv new and useful Improvements in RefrigeratorAttachments. of which the following is a specification.

This invention relates to traps for refrigerators and has for itsprimary object the provision of a device of this character which may beconveniently connected with an ordinary drip pipe to receive thedrippings therefrom. and to form a water-seal at the base of the pipeoutside of the refrigerator and thereby close the pipe against a directadmission of warm atmospheric air thereto.

Another object of the invention resides in the provision of anattachment for refrigerators functioning as a preservative of therefrigerant by closing the lower .end of the drip pipe by a water-sealwherein the cold drippings from the refrigerant chamber will bepermitted to accumulate and then overflow into a suitable wastereceptacle.

Another object of the invention resides in the provision of a device ofthis character which will be adjustable upon the drip pipe so thatrelative separation of the parts can be effected to permit the device tobe readily cleaned when desired.

With the alcove and other objects in view which will appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangements of parts which willhereinafter be fully described and particularly pointed out in theclaims.

In the accompanying drawings, has been illustrated, a single andpreferred form of the invention, it being, however, understood that nolimitations are necessarily made to the precise structural detailstherein exhibited, but that changes, alterations and modiiications,within the scope of the claims may be resorted towhen desired.

Figure 1 is a front view of a refrigerator with parts broken away andparts in section, illustrating the application of the invention thereto.

Fig. 2 is a side view of the attachment and a port-ion of the drip pipe.

Fig. 3 is a vertical section therethrough,

Specification of Letters Patent.

Serial No. 248,158.

The invention is designed principally for use in connection withrefrigerators of the type conventionally illustrated at 5 wherein 1sincluded a chamber 6 for the refrigerant and drip pipe 7 leading fromthe chamber and extending through the bottom of the refrigerator in thecustomary manner so that the waste drippings can be conducted to asuitable pan or receptacle when placed beneath the refrigerator.

Beneath the lower end of the drip pipe 7 is a sealing cup 8 which isprovided upon its base wall with up-struck radial ribs 9. The side wallsof the cup are spaced from the lower end of the drip pipe 7 and incidentto the radial arrangement of the ribs 9, it will be observed thatintervening discharge spaces 10 are formed between said ribs so as toprovide for a proper discharge of the ldrippings from the pipe 7. Risingfrom the center of the cup is a vertical stem 11 which is arranged toenter the drip pipe 7 and as shown, said stem is provided with an eye12, which has detachable connection with a snap fastening 13 on thelower end of a suspending and adjusting connection-14. The suspendingand adjusting connection is preferably in the form of a chain, the sameeX- tending through the drip pipe and terminating in a free end 15adapted to be disposed in the refrigerating chamber beneath the tray 16.This free end is provided with a pin 17 which is adapted forinterchangeable connection with the links of the chain and said pin isof a length appreciably greater than the maximum diameter of the drippipe whereby it may be passed over the upper end of the drip pipe torest thereon and thereby hold the cup against the lower end of the drippipe and actively suspend the same therefrom.. The arrangement is suchthat when it is desired to clean the cup 8, the pin 17 can be removedfrom its link of the chain and the cup lowered until the snap fastening13 at the lower end of the chain is exposed. 1When this is accomplishedthe cup can be entirely removed at the convenience of the operator andcleansed or sterilized and thereby always maintained in a highlysanitary condition. When the cup is in its normal position the drippingsfrom the refrigerating chamber accumulate in the cup and form awaterseal for the drip pipe and the pipe is in this mannersatisfactorily closed against the admission of Warm outside air to therefrigerating chamber. It is found that With the device in use therefrigerant is preservedl 5 against undue Wastage. What is claimed asnew is 1. A trap for refrigerators comprising a cup,v a chain connectedWith the cup and adapted to pass through the drip pipe, and

10 means adapted to coact With the chain and With the drip pipe to holdthe cup suspended from said drip pipe.

2. A trap for refrigerators comprising, a cup, a chain carried by thecup, and a pin interchangeably connected with the chain 15 and adaptedto engage With a Xed support to hold the cup in an adjusted position.

In testimony whereof I aiiix my signature.
